He tries not to think too much in the morning, but by night the problems of the universe keep Stephen Hawking awake. Fellow physicist Brian Cox asks him about the big issues facing science.

Physicist Stephen Hawking got the world’s attention a long time ago. The brilliant scientist, trapped in wheel chair and Lou Gehrig’s disease, whose mind encompassed the cosmos.
In “A Brief History of Time”, Hawking laid out what we knew of the universe in compelling imagery and metaphor.
Now he’s back, with physicist Leonard Mlodinow, for a cosmic update. Not one universe out there, but many, they say. And no need now for God to explain the origin of everything. Science, they say, will do it.
A new warning from astrophysicist and global science guru Stephen Hawking: Do not talk to aliens.
The brilliant Hawking is wheel-chair bound and speaks through a computer. But he’s thinking about the cosmos.
With billions of galaxies, trillions of stars, the numbers tell him there’s life out there. The smartest forms could make it here. But we should not want that, says Hawking. Too much danger.
Other scientists disagree. We’ll hear that debate, and talk to the man who heads Earth’s greeting committee for aliens.
